I was asked to referee a mathematics article, submitted for publication in a reputable journal. To evaluate it, I also wanted to look at a cited article which it claims to extend. Upon searching online (through my university's VPN) I hit a paywall: I can read it for "only" $39.95.
My university subscribes to some journals, but apparently not this one. I find this price ridiculous and I will not pay. But I am also reluctant to ask my library to; that money is coming out of our students' tuition. If I ask a librarian to furnish me with a copy of the article, will they be out this same $40?
Related question: will publishers (requesting that I do peer review for them) obtain and provide articles upon request, in situations like this?
Update: People gave me the (excellent!) advice to ask my librarians, and they got back to me. Their answer in brief: It depends. Usually, it doesn't cost my library anything; sometimes it can, but the requests go through different channels than the paywall I encountered.
